SPECIFICATION forming part of Letters Patent No. 604,518, dated May 24, 1898.

' Application iiled January 29, 1897. Serial No. 621,209. (No model.)

To ctZZ whom t may concern: Y

Be it known that I, EDWARD T. BURGnss, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Plumbers Furnaces, of which the following is a specification.

My invention relates to the improvement of plumbers furnaces of that class which are adapted for heating soldering-irons or melting metal and which employ gasolene or similar fuel. Y

The objects of my invention are to provide an improved furnace of this class of superior construction and arrangement of parts, to provide a plumbers furnace wherein are combined improved means forproducing a blowpipe or ordinary flame and admit of the same being used separately or together, and to provide other improvements in details ,of construction and arrangement of the operating parts, which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of my improved plumbers furnace. Fig. 2 is a central vertical section of the same. Fig. 3 is a plan view with the parts above the burner removed; and Fig. 4E is a detail sectional view of a portion of the burner iiaring flame-ring, which I employ in the manner hereinafter described.

Similar numerals refer to similar parts throughout the several views.

In the construction of my device I employ a base in the form 0f a suitable gasolene tank or can 1. This tank has connected therewith a combined iilling-plug and valve 2, with which is connected the usual flexible bulbholding air-tube 3, through the medium of which air is forced into said can to place the gasolene therein under pressure. Rising from the upper and preferably inner side of the can ortank 1 is avertical supply-pipe lawhich is provided adjoining said can with a suitable valve 5. The upper portion of the pipe 4l is provided with an inwardly-extendin g arm 6, which above the center of the tank is converted into a generator-coil 7. The lower end of this coiled pipe-arm connects at 8 with a transverse pipe-arm or valve-tube 9, the latter being thus supported below said coil and above the tank. Immediately beneath the central portion of t-he vertical coil 7 the valvetube 9 is provided with a needle-point valveoutlet 10, whichis controlled by a valve-rod 11, which extends into said valve-tube 9 and has a threaded engagement with the outer end thereof in the usual manner. The remaining end portion of the valve-tube 9 is closed, but is provided on its upper side with a needlepoint opening at 12, which is controlled by a Vertical valve 13, which has a threaded engagement with a downwardly-extending boss 14 of said tube.

15 represents a burner, the body of which is substantially in the form of a hollow ring, and the inner wall of which is provided at intervals with substantially vertical slotted openings 16. Above the slotted burner-openings 16 and adjacent to the upper side of the burner said inner wall is provided with a continuous circular slot 16a. This circular or ring burner is provided on one side with an outwardly-extending supply-neck 17 and is recessed, as indicated at 1S, to receive the inwardl y-eXtendin g arm portion 6 of the pipe 4.

The burner 15, which is made to surround the upper portion of the vertical coil 7, has rising from about its mouth or upper end portion a flaring flame-protecting band or shield 19, the latter having its lower end portion flanged inwardly, as indicated at 20, this inwardly-flanged portion forming a hood to protect the slotted opening 16 for the purpose hereinafter described. Upon the upper side of the flaring flame-ring 19 is supported a suitable plate 22, the outwardly-extending peripheral lugs of which are connected by means of vertical bolts 23 with the upper side of the tank 1. These bolts also pass through flange-lugs 19n on the ring 19 and through the upper ends of brace or supporting arms 24, which rise from the burner-body, thus insuring' the support and retention of said burner and flame-ring in their proper positions.

Upon the upper side of the plate 22 may be supported a desirable form of detachable melting-pot or soldering-iron holder 25.

The outwardly and downwardly extending neck 17 of the burner is provided with a short vertical tube extension 26, which, as indicated inthe drawings, is immediately over the IOO needle-point valve-opening 12 of the valvetube 9.

27 represents a drip-cup which has its upper end portion secured about the base of the burner-body, from which said cup depends. This drip-cup is provided at intervals with openings 28, and through two of these openings, which are oppositely located, passes the valve-tube 9.

The manner of utilizing my improved plumbers stove is substantially as follows: In case it is desired to utilize the burner 15 the valve 5 is opened, allowing the gasolene under pressure within the can or tank to rise in the pipe 4 and pass through the coil 7. By then opening the valve 11 and allowing the same to remain open a sufficient length of time a small quantity of the gasolene is allowed to escape through the needle point opening and drip downward into the cup 27. 'Ihe valve 11 being closed, the gasolene contained within the cup may be ignited and the heat imparted therefrom to the coil, resulting in the generation of gas in said coil. The valve 13 being now opened, the gas which has passed from the coil-pipe into the valvetube 9 is discharged through the needle-point opening 12, and mixed with the air passes into the tube 26 and burner-neck 17 and out through the slotted openings 16 and 16:,where it may be ignited. The fiame which rises from the slotted burner-openings 16 and 16L is prevented from flaring outward and retained beneath the plate 22 by the iaring flame-protector 19. In this manner the direct heat from the burner is imparted to the irons contained in the holder 25. In case it is desired to combine with the flame above described a forced or blowpipe iiame the Valve 11 may also be opened, allowing the gas to pass outward through the needle-point opening 10, and by force of the air-pressure within the tank the gas thus escaping will be driven through the center of the coil 7, at the top of which it may be lighted. Owing to the volume of gas which escapes from the valveopening 10 being ignited without passing through a burner or being otherwise interfered with, it is obvious that the flame produced therefrom must be in the nature of what is known as a blowpipe or forced flame, while the flame arising from the burner-slots is what may be termed a comparatively tame flame. If desired, the valveopening 12 may be cut off and the blowpipeflame employed alone.

In the manner above described it will be seen that simple and reliable means are com-y bined in one furnace for the production of either an ordinaryT heating-flame or blowpipeiiame, or both.

By providing the lower end portion of the flame-protecting band 19 with the inwardlyprojecting flange 2O a hood or shield is provided above the slot 16, which prevents any tendency of the solder dropping within said slot from the irons or metal-pot.

The construction and arrangement of the parts of my improved furnace are such as to provide a furnace of a strong, durable, and neat construction and at a reasonable expense.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a plumbers furnace the combination with a burner 15 having burner-openings therein, of a generating pipe-coil 7 having connection with a tank and a valve-tube 9 connected with said coil, said valve-tube being provided with valve-openings 10 and 12 adapted to discharge respectively through said coil and into said burner, substantially as and for the purpose specified.

2. In a plumbers furnace the combination with a hollow circular burner body or ring having burner-openings on its inner side and means for discharging gas into said burner, of a daring dame-protecting ring rising from said burner-top and an inturned flange portion 20 formed on the lower end of said protector-plate and adapted to form a protecting-hood for the burner-openings, substantially as and for the purpose specified.

3. In a plumbers furnace the combination with a hollow circular burner-body having a gas-receiving neck 17 and having a continuous horizontal burner-openin g 16a in its inner wall, and substantially vertical burner-openings 16 below said burner-opening 16a, of a tank 1, a generating-coil burner encircled by said burner-body and connected with said tank, a valve-tube connected with said coil and supported therefrom and valve-controlled openings in said valve-tubes adapted to discharge respectively through said coil 4and into said burner-neck, substantially as and for the purpose specified.
